History Trivia / DoctorWhoS8E5TheDaemons

* CastTheExpert: Damaris Hayman had an interest in the supernatural and helped out during production as an unofficial adviser. A friend of hers was a practising witch, who had commended the scripts for their accuracy.

* CreatorsFavouriteEpisode: Creator/JonPertwee named this as his favourite serial, while Creator/NicholasCourtney named it his second favourite after "[[Recap/DoctorWhoS7E4Inferno Inferno]]". Director Christopher Barry also named it as his favourite, saying it was "a damn good script".

* {{Corpsing}}: In the long shot just after the Doctor gets caught up in the middle of the Morris dance when they all round on him and begin hitting him with their sticks and bladders, you can see Creator/JonPertwee is cracking up. (Despite the ludicrous description, this is supposed to be a scary scene.)

* PopCultureUrbanLegends: The "missing sixth episode", set off by an April Fool's prank in a fanzine. The somewhat abrupt and ill-explained ending of the story, combined with its unusual length of five episodes, led to a fan rumour that it was made as a six-part story and then had the last two episodes crudely edited into one. This had happened a couple of times earlier in the show, with "[[Recap/DoctorWhoS2E1PlanetOfGiants Planet of Giants]]", and "[[Recap/DoctorWhoS6E1TheDominators The Dominators]]", but this was written as broadcast.

* HostilityOnTheSet: Director Christopher Barry was trying to shoot a sequence where an invisible heat barrier singes the ground, an effect by the location being hit by a freak snowstorm in early May. After a series of delays, Barry announced it might not be possible to get the scenes in the can after all, at which point Creator/JonPertwee fired up the Doctor's motorbike and drove off in a huff.

** Relations between the star and the director were already strained, after plans to film one Sunday were shelved so that Pertwee could perform one of his regular cabaret engagements in Portsmouth, despite Barry having missed his sister's wedding to be on set.

* ThrowItIn: Yates and the Brig's dialogue at the end, where the former cheekily asks the Brigadier if he wants to dance and the Brig replies that he'd rather have a pint, was ad-libbed by Richard Franklin and Nicholas Courtney.

* AlanSmithee: Writers Robert Sloman and Barry Letts are credited together under the pseudonym of "Guy Leopold," as Sloman was under contract elsewhere at the time, while Letts was not allowed to be credited with any additional role alongside his producers' credit. Sloman would be credited under his own name for his remaining stories on the show, though Letts was never credited on-screen as a writer.

* WhatCouldHaveBeen: Creator/NicholasCourtney suggested including the Brigadier's wife, whom he proposed might be called Fiona. Creator/TerranceDicks was not in favour of this, however, and it was not included in the scripts. The character would eventually debut in the Literature/PastDoctorAdventures as the Brigadier's first wife, and mother of Kate Stewart.
